CHP Demonstration at The New York Racquet and Tennis Club(ST8580-1)
The First Energy Group, Inc.
Located in downtown Manhattan, the NY Racquet and Tennis Club spends more than $382,000 per year in energy costs to run its facility. This facility operates approximately 18 hours per day, year round, and requires electric power with a demand ranging from a minimum 268 kW (nighttime in winter) to a maximum 464 kW (daytime in summer). The facility operates two boilers fueled by #6 oil to produce low-pressure steam, which is used year-round for domestic hot water. The facility has substantial thermal load throughout all hours of the day, due to locker room showers and kitchen food preparation activities, laundry services, swimming pool heating, and space heating throughout the heating season. The facility displays a coincident electric and thermal demand that occurs for a significant number of hours per year, and therefore represents a good candidate for installation of a Combined Heat and Power (CHP) system.
Through this project, the New York Racquet & Tennis Club has installed a microturbine-based CHP system in a provocative “hot windbox” configuration; high-temperature exhaust from the microturbine (circa 450 degrees F), which still contains plenty of oxygen, is fed as “combustion-supply air” to one of the boilers. That boiler has been renovated to now burn natural gas. The CHP system consists of two microturbine induction generators, manufactured by Ingersoll-Rand, rated at 70 kW each. The generators have been installed and will be operated interconnected with and in parallel with the local electric utility grid in the electric service territory of Consolidated Edison Company of New York, Inc. (Con Edison). Use of the CHP generator will replace approximately half of the electricity currently purchased from the grid, and replace about half of the heat currently produced by combustion of #6 oil in the boilers. Challenges involve proper design of ducting and control of flow-balancing dampers to direct the microturbine hot exhaust to the boiler when needed, or some or all to a chimney vent when not needed, as well as to bring some ambient air to the boiler as “combustion supply air” to supplement the microturbine exhaust when needed.
This project is forecast to provide peak load reduction of approximately 140 kW, and result in over $65,000 in annual net energy savings for the host site facility. It is forecast that the new system will have an overall annual fuel use efficiency of at least 70%. Technology transfer and publicity will emphasize the efficacy of this CHP system.
After a one-year delay due to the moratorium impacting installation of microturbines in New York City imposed while the City Department of Buildings and Fire Department established new rules, the microturbine system started operation in March 2010.
